The values of Preferred measurements for length L are found, for example, between 360 mm and 600 mm, and for width B, for example, between 250 mm and 430 mm. The surface has a support side, which is made hereinafter referred to as support surface 02, with which the elevator 01 rests in the state arranged on a surface side 07 of a cylinder 06. The rear of the surface of support 02 is a work surface that, in the event that the elevator 01 is shaped like a printing mold 01, it is provided with a print layout, or at least you can Provide a print layout. Elevator 01 has two ends 03; 04 opposite each other, preferably with sides pendants 13; 14 bent respectively, limiting the ends 03; 04 the support surface 02, and extending the sides pendants 13; 14, respectively, preferably completely or at least partially along the width B of the elevator 01. The support surface 02 of the elevator 01 is flexible at least along the length L, and in an arrangement of the elevator 01 is you can adjust the side surface 07 of the cylinder 06 to your curvature (Fig. 2). When the printing mold 01 is arranged on the lateral surface 07, the length L of the support surface 02, thereby, in the direction of the contour of the cylinder 06, whereby the width B of the bearing surface 02 extends in the axial direction of the cylinder 06.

As shown in Fig. 2, the sides pendants 13; 14 of the elevator 01 are fixed by means of a fixing device, the device being arranged clamping on a channel 08, extending channel 08, as a rule general, in the axial direction towards the cylinder 06. One end 03 of the elevator 01 oriented in the same direction as the direction of Production P of cylinder 06 is designated as its end 03 forward, while the opposite end 04 is the end 04 delayed elevator 01. At least ends 03; 04 of elevator 01 with hanging sides 13; 14 conformed in them they are formed by a rigid material, for example metallic, by example of an aluminum alloy. Usually, the thickness of the material D of elevator 01 (Fig. 1) or the thickness of material D to less than the hanging sides 13; 14 has a value of few tenths of a millimeter, for example 0.2 to 0.4 mm, preferably 0.3 mm. With this, the elevator 01 is formed in its entirety, or at least at its ends 03; 04 of a stable material in form, so that ends 03; 04 can be stably deformed by means of a flex against a specific resistance of material.

At least at one end 03; 04 of elevator 01 (Fig. 1), preferably, however, at the two ends 03; 04, they are formed along a bending edge 11; 12, respectively, a bent pendant side 13; 14, rotting introduce the hanging sides 13; 14 in an opening 09 of the channel 08 of cylinder 06 (Fig. 2) narrowly shaped, in particular, in slot shape, and being able to fix there by means of a device  for fixing, for example a clamping device. For example, it is folded referring to the length L of the support surface 02 flat, not bulging, of elevator 01 not mounted at its end 03 a hanging side 13 at the bending edge 11 at an opening angle α1, or at its end 04 a hanging side 14 on one edge bending 12 at an opening angle β1 (Fig. 1), being the opening angles α1; β1, for example, between 30 ° and 140º. When the opening angle α1 is assigned to the front end 03 of elevator 01, then this is done, preferably, at an acute angle, in particular it has a value of 45º. The opening angle β1 at the leading end 04 of the elevator 01 is usually preferably formed greater than 80º, or in obtuse angle, in particular it has a value of 85º or 135º. The hanging side 13 folded at the leading end 03 has a length 113 that is, for example, in the range of 4 mm to 30 mm, in particular between 4 mm and 15 mm. The hanging side 14 folded at the end 04 delayed has a length 114 which has a value, for example, from 4 mm to 30 mm, in particular between 8 mm and 12 mm, the shortest length measurement being preferred to ensure as simple as possible removal of the hanging sides 13; 14 of opening 09 of channel 08.

Fig. 2 shows in a representation in simplified section a 0G cylinder with a side surface 07 and a channel 08, which presents towards the lateral surface 07 a narrow opening 09, in the form of a groove, with a groove width S, having a value the groove width S, less than 5 mm, and preferably in the range of 1 mm to 3 mm. Opening 09 presents a production direction P of the cylinder 06 an edge 16 front and a rear edge 17. Between the wall 18 that extends from leading edge 16 towards channel 08 and a T09 imaginary tangent found on the lateral surface 07 of the cylinder 06 in the opening 09 an angle of α2 opening having a value between 30º and 50º, preferably 45º. The hanging side 13 folded at the end 03 front of elevator 01, with it, it can be hung on this edge 16 front of the opening 09 preferably by dragging shape, since the opening angle α1 at the end 03 front of elevator 01 is preferably adapted to the angle of opening α2. Similarly behaves at end 04 delayed elevator. Between the wall 19 that extends from the trailing edge 17 towards channel 08 and an imaginary tangent T09 which is located on the side surface 07 of the cylinder 06 in the opening 09 is formed an opening angle β2, which It has a value either between 80º and 95º, preferably 90º, or between 120º and 150º, preferably 135º. The hanging side 14 folded at the leading end 04 of the elevator 01, thereby you can hang on this rear edge 17 of the opening 09, preferably by dragging, since the angle of opening β1 at the leading end 04 of the elevator 01 is adapted, at least approximately, to the opening angle β2.

On channel 08 they are arranged, for example, at minus a holding means 21 housed so that it can be done preferably, and a prestressed spring element 22, preferably, in which the spring element 22 presses the fastening means 21, for example, against the hanging side 14 folded at the leading end 04 that is hung in the opening 09 at its rear edge 17, thanks to which the hanging side 14 at the leading end 04 it is held on the wall 19 which extends from edge 17 posterior to channel 08. To relieve pressure exerted by the clamping means 21 is provided in a channel 08 a regulation means 23, preferably regulation means 23 that can be operated pneumatically, which when activated makes swing to the clamping means 21 against the force of the element of spring 22. The clamping device described by way of example It is formed, according to this, essentially by the clamping means 21, the spring element 22 and the regulating means 23.

Cylinder 06 described by way of example is created, for example, in such a way that on its lateral surface 07 several elevators 01 can be arranged, preferably the same kind. When cylinder 06 is configured as a cylinder of intaglio, this can be occupied in its axial direction with up to six printing molds 01 in the form of a plate, for example, one next to each other. It is also preferably provided that in the cylinder 06, in the direction of its contour, be arranged more than an elevator 01. Thus in the cylinder 06 they can be provided under its lateral surface 07, for example, two channels 08 that run axially with respect to cylinder 06, which stops fixing of elevators 01 have openings 09 that run axially to the cylinder 06, the openings 09 being arranged in the contour of the cylinder 06, for example offset 180º from each other when in cylinder 06 they have to be arranged along their contour, one after another, two elevators 01. With this occupation of cylinder 06 with two elevators 01 arranged along its contour one after another, the leading end 03 of an elevator 01 is set to channel 08, while the late end 04 of the  same elevator 01 is fixed on the other channel 08. For the rest of elevators 01 arranged in this cylinder 06 occurs what correspondent. When in the axial direction of the cylinder 06 are arranged, next to each other, several elevators 01, these too they may be advantageously disposed, displaced from each other. He displacement may refer, for example, to elevators 01 individual or groups of elevators 01, which are arranged, by for example, displaced by each other a half length L of elevator 01, what conditions, however, that others are introduced channels 08 with assigned openings 09, or at least with parts partials thereof in cylinders 06 that are arranged displaced along the contour of the cylinder 06 with respect to the channels 08 and openings 09 mentioned above, for example, in 90º.

An example of an example is described below. procedure for mounting a flexible elevator 01 in a cylinder 06 of a printing machine, in which cylinder 06 is can be arranged along its contour, one after another, two elevators 01, and in which each elevator 01, referred to the direction of production P of cylinder 06, has an advanced end 03 and a backward end 04 (Fig. 3). At the 03 advanced end of elevator 01 is formed a hanging side 13, in which this side pendant 13 is bent with respect to the extended length L of the elevator 01 with an opening angle α1 of a maximum of 90 °, preferably 45º. At least one cylinder is provided in cylinder 06 opening 09 preferably in the form of a groove with a first edge 16 in the production direction P of the cylinder 06 and a second edge 17, running edges 16; 17 in the axial direction of cylinder 06 preferably parallel to each other. The end 03 Advance of elevator 01 is supplied, for example, by means of a shear force 01 that attacks at the end 04 delayed from the elevator to the cylinder 06, preferably tangentially in its production direction P, until the pendant side 13 is in contact at the end 03 advanced after the second edge 17 of the opening 09 with cylinder 06, so that the hanging side 13 shaped at the leading end 03, with a rotation of the cylinder 06 in its production direction P, as a result of a force radial FR acting at least on the leading end 03, oriented towards the cylinder 06, penetrates the opening 09 and hooks on the first edge 16. In case the elevator 01 be raised with its hanging side 13 shaped at end 03 forward on the side surface 07 of the cylinder 06 performing a support, then the radial force FR may be, for example, the gravity force FG acting on the lateral surface 07 of cylinder 06.

In addition to the use of the force of the gravity FG of the elevator 01, or alternatively to this, the end Advance 03 of the elevator 01 can be prestressed elastically (Fig. 4), so that the hanging side 13 formed at the end 03 advanced, as a result of an MR oriented straightening moment towards cylinder 06, it elastically enters the opening 09, as soon as the opening 09 of the cylinder 06 and the contact line 27 of the pendant side 13, with the surface side 07 of cylinder 06, as a result of a movement relative between the elevator 01 and the cylinder 06, the relative movement, in particular, by rotating the cylinder 06 in the production direction P.

The straightening moment MR results from the elevator 01 is made of an elastically deformable material, and thereby immanently possesses a spring characteristic elastic, using this feature as the end 03 front of elevator 01, when approached to cylinders 06, by example, it is guided along an edge 26 of an element of support 24 which preferably runs axially with respect to the cylinder 06, spaced apart from cylinder 06, and there bends in such a way that at the leading end 03 of the elevator 01 a bending tension with a spring force is established oriented towards cylinder 06 (dashed representation of elevator 01 in Fig. 4). At least until the end 03 guided along the edge 26 of the support element 24 of the elevator 01 is on the side surface 07 of the cylinder 06, the elevator 01 is supplied with its end 04 delayed from a spatial direction fixed with respect to cylinder 06. the elevator 01, according to this, is stabilized during the assembly process to through the contact line 27 of its pendant side 13 placed in the end 03 advanced with the lateral surface 07 of the cylinder 06, as well as by means of its support at the edge 26 of the element of support 24, and by means of a position fixation 28 of the end 04 delayed. The support element 24 may be shaped, by example, as a rolling element 24, in particular as a cylinder 24 or as one or more rollers 24 arranged one next to the another axially to cylinder 06, which can be or can be placed, by example, in the function of a pressure element 24, in contact with the cylinder 06. The support element 24 is arranged, by example, near cylinder 06.

The leading end 03 of the elevator 01 also can be approached towards cylinder 06 such that this end 03, after touching the side surface 07 of the cylinder 06 under an acute γ angle with a second tangent Imaginary T29, which is located at a contact point 29 in the side surface 07 of cylinder 06, deviate from the surface side 07 of cylinder 06 (representation of elevator 01 in the Fig. 4 with solid line). The bending made of this way of the leading 03 end of the elevator 01, however, only it must be so strong that the hanging side 13 placed there safely contact the side surface 07 of cylinder 06. To support the safe contact of the side pendant 13 with the lateral surface 07 of the cylinder 06 can be, for example, contacting the support element 24 with the elevator 01, thanks to which elevator 01 is held with its end 03 forward near side surface 07 of cylinder 06.

During the relative movement between the cylinder 06 and the elevator 01, preferably during the rotation of the cylinder 06 in its production direction P, but also during a proper movement of the elevator 01, for example against the Production direction P of cylinder 06, the hanging side 13 is hooked on the leading end 03 of the lift 01 on the first edge 16 of the opening 09. A rolling element 24 placed in contact with the cylinder 06 can in this case support the assembly of the elevator 01 on the cylinder 06, making the element of rolling 24 wind the elevator 01 over the cylinder 06. In the leading end 04 of the elevator 01 is formed the side pendant 14, pressing this pendant side 14 by the element of rolling 24 in the course of the winding of the elevator 01 over the cylinder 06 in opening 09 of cylinder 06.

For this purpose, approximate openings o38; o39 of the printing mold store 38; 39, referring to an opening 09 in the cylinders of gravure 31; 33 to the gravure cylinders 31; 33 to one distance a38; a39 clearly less than the value of length L of printing molds 36; 37. Distances a38 are advantageous; a39 between 2% and a maximum of 50% of the length L of the molds printing 36; 37, in particular distances a38; a39 short of up to 10% of the length L. The fact of that at least the printing mold container 39 provided by above the paper strip 46, be arranged in a mobile way, so that this deposit of printing molds 39, from a position of rest that is preferably above the mechanism printer, can be approximated or can be tilted approaching the rotogravure cylinder 33 to a working position, for example. By means of the mobile arrangement of mold deposits printing press 38; 39 results in better access to the printing mechanism, by example for the realization of the works that are required there, for example maintenance work. In the work position, vats 41; 43 or 42; 44 of the printing mold deposits 38; 39, or at least the mold storage positions printing 36; 37, are preferably oriented so horizontal or with a slight inclination, preferably with less 15º with respect to the horizontal H, pointing the opening o38; o39 of printing mold deposits 38; 39, advantageously, to a of the openings 09 in the rotogravure cylinder 31; 33 with which  the printing mold tank 38 acts together; 39 correspondent.

A deposit of printing molds 38; 39 arranged in a mobile way can be fixed in its working position in front of a gravure cylinder 31; 33 at your distance a38; a39 and in its orientation with respect to the gravure cylinder 31; 33 by means of a movable stop 48 (Fig. 5). The mobile stop 48 is I could perform, for example, by means of a conical bolt, which, by example, it is fixed in its position referred to the cylinder of gravure 31; 33, and penetrates an opening in the housing of the printing mold deposit 38; 39, and centers a deposit of printing molds 38; 39 approximate by tilting to the cylinder of gravure 31; 33 with its openings o38; o39 in relation to bulging of the rotogravure cylinder 31; 33. Represents a advantage of carrying the gravure cylinder 31; 33 regarding the lateral register to a predefined position, set it to zero, for example, with respect to the lateral register before it produce an exchange of a printing mold 36; 37 between gravure cylinder 31; 33 and the printing mold store 38; 39. Alternatively to the gravure cylinder adjustment 31; 33, the deposit of printing molds 38; 39 you can also carry, laterally in relation to the gravure cylinder 31; 33, to a predefined position, so that the exchange of a mold of printing press 36; 37 between the printing mold tank 38; 39 and the gravure cylinder 31; 33 can be done in an oriented way and without lateral displacement.

It is advantageous to arrange near the cylinder of gravure 33, in front of the mold tank opening printing 39 orientable on the gravure cylinder 33 a conductive plate 49 housed in an articulated manner, preferably tiltable (Fig. 5), with which an end 04 of a mold is guided printing press 37 delayed detached from an opening 09 in the cylinder of rotogravure 33 so that it is oriented towards the tank 42 for housing of the printing mold 37 to be removed. In in particular, with the conductive plate 49 it is locked for a mold of press 37 to be released from the gravure cylinder 33 incorrect access to Cuba 44, in which at least provides, or at least a new mold of can be provided printing 37. Similarly, in the printing mold store 38 arranged below the paper web 46, which acts together with the gravure cylinder 31, it can be advantageous the placement of a conductive plate 49, which, without However, for reasons of visibility, it is not represented in Fig. 5.

Another embodiment for a machine printer with printing mold deposits results jointly with a printing machine, for example an offset printing machine of various colors, whose printing mechanisms are arranged preferably in a bridge construction mode or in a mode of compact construction in eight, that is, in a printing machine built low in its constructive height with eight positions of printing, as shown, for example, Fig. 36, in at least a frame 97 on a base 96, one on the other. A material of print 46, preferably a paper web 46, is supplied in this case to the printing machine, and it is driven vertically through the printing mechanisms. In Fig. 36 they are represented, by way of example, four printing mechanisms Consecutive in the transport direction of the print band 46, which present to the right and to the left of the paper band 46, respectively, a transmission cylinder 32; 34 with a gravure cylinder 31; 33, rolling the cylinders together  transmission 32; 34 opposite each other in a printing mechanism in the paper band 46.

The paper web 46 approaches, for example, by means of a first paper driving roller 92 arranged before the first printing mechanism to the first printing mechanism, and by means of a second paper driving roller 93 arranged after the fourth printing mechanism is removed from the room printing mechanism To each gravure cylinder 31; 33 is assigned at least one inking mechanism 94, on whose particularities do not enter here in more detail. To each cylinder gravure 31; 33 is assigned a deposit of molds of printing press 38; 39, which preferably presents corresponding, two vats 41; 42; 43; 44. As in the exemplary embodiment described above in conjunction with the Fig. 5, also here, each tank of printing molds 38; 39, at least its storage position for a printing mold 36;  37 to be stored, is oriented in the position of I work primarily primarily horizontally or just with a slight inclination of less than 15º with respect to the cylinder of gravure 31; 33. In the working position of the deposit of printing molds 38; 39 at least one mold can be exchanged printing 36; 37 between vats 41; 42; 43; 44 and the cylinder of gravure 31; 33, or by removing a mold of printing press 36; 37 that is no longer required for the realization of a print job of the rotogravure cylinder 31; 33, e introducing it in Cuba 41; 42, or removing a new mold from printing press 36; 37 for carrying out the printing task of the Cuba 43; 44, and mounting it in the rotogravure cylinder 31; 33. The constructive characteristics of deposits for molds of printing press can correspond in this embodiment with those of the embodiment described above jointly with Fig. 5. Represents an advantage when the embodiment, in particular the execution of a change of printing mold is supervised by sensors. Similarly, deposits for printing molds 38; 39 can be controlled together with gravure cylinders 31; 33 such that, preferably, from a command post assigned to the machine printer, you can selectively order a mold change of printing. Since the printing mold deposits 38; 39 se can prepare during a running production of the machine printer for a change of printing mold, the time is reduced of equipment that requires a stop of the mechanisms printers at an extraordinarily short time interval of, for example, less than two minutes, preferably less than ninety seconds, for a complete change of all the molds of printing press 36; 37 of the printing mechanisms provided in this printer machine Depending on the configuration of the printing mechanisms, in the described printing machine can be using, for example, ninety-six printing molds 36; 37 to Same time. A change of printing mold so fast, with a greater number of printing molds 36; 37, increases the profitability of the printing machine in a considerable way as consequence of its extraordinarily short stop time.

Other particularities related to a procedure and to a device for carrying out the procedure are now explained by way of example from Fig. 6 to 35. In this case, Fig. 6 shows a cylinder of gravure 33 with two channels 08 displaced in the 180º contour, and two printing molds 37 arranged along contour one after another, in which the pendant side 14 bent at right angles in the 04 end delayed in the production direction P of the gravure cylinder 33 of each printing mold 37, is held by means of a clamping means 21 arranged in the channel 08, pressed by a spring element 22, on a wall 19, the wall 19 extending from a rear edge 17 of an opening 09 that opens channel 08 towards channel 08, being able to detach the clamping means 21 by means of actuating a means of 23 pneumatic regulation that opposes the spring element 22. On the wall 18 extending from the leading edge 16 of the same opening 09 towards channel 08 is set by dragging form the hanging side 13 bent at an acute angle at the end 03 advance of the other printing mold 37 arranged along the contour of the rotogravure cylinder 33. For particularities referred to the clamping of printing molds reference is made to Fig. 2.

Fig. 6 further shows an element of pressure 24 adjustable by means of pneumatic drive to gravure cylinder 33 in the form of a clamping cylinder 24 or a tightening roller 24. Similarly, near the cylinder of gravure 33 an orientation device 51 is provided housed so that it can be tilted parallel to its axial direction, with two stops 52; 53 wing-shaped arranged diametrically, which act laterally on the printing mold 37, in which the orientation device 51, respectively, with one of its stops 52; 53, fixes a printing mold 37 that has been to mount 37 during its approach to the gravure cylinder 33 Regarding lateral registration. In this case, the stops 52; 53 are respectively formed as a lateral guide plate, in the that stops 52; 53 are arranged, for example, on a crossbar tiltable, for example in a square tube. The stops 52; 53 se they differ, for example, in their position referring to the address axial of the gravure cylinder 33, so that, for example, for a printing mold 37 of simple width the stop 52 is used, and for a printing mold 37 in panoramic format the stop 53 by means of a corresponding tilting of the device  of orientation 51. The stops 52; 53 can be adjusted axially with respect to the rotogravure cylinder 33 for the required width of the printing mold 37.

From Fig. 6 other ones can also be extracted particularities of the printing mold deposit 39. The example of embodiment shown in Figs. 6 to 35 part of a variant for the printing mold store 39 in which a tank 44 upper can be operated for the preparation of a mold press 37 to be mounted on the gravure cylinder 33 as its own constructive unit regardless of a tank 42 bottom for housing a printing mold 37 removed of the rotogravure cylinder 33. The two vats 42; 44 can be use as individual building units that can be used independently of each other, and with it in order of operation independently. This application is interesting when, by For example, only the cylinder load must be automated gravure 33 with new printing molds 37, made by on the contrary, the withdrawal of printing molds 37 used by a operator. When the two vats 42; 44 are conformed in the printing mold tank 39, an exchanger of fully automatic printing molds. The two vats 42; 44 present all the devices required for storage and transport of printing molds 37, and are constructed preferably in a very compact way. In particular, despite its reception capacity of at least two printing molds 37, It has a reduced construction height. Constructive height it has a value, for example, of more than 150 mm, preferably of less than 100 mm

In the exemplary embodiment shown in the Fig. 6 to 35, bowl 44 is arranged horizontally, and oriented tangentially Thanks to this, the force of gravity FG exerted on the printing mold 37 is used to support the functions described below in the best possible way. In Cuba 44, find a support 54, with which you can contact, or it can separate, a first printing mold 37 to be mounted on the rotogravure cylinder 33 with its hanging sides 13; 14 bent A printing mold 37 placed on the support 54 is arranged there, for example, with its entire length L extended. He support 54 preferably is not conformed in all the surface, but in the form of parallel slats 54 or rails of sliding 54. The hanging side 14 at the end 04 delayed the First printing mold 37 is located in Cuba 44 on the opposite the gravure cylinder 33 in contact with a stop 56 which is preferably placed vertically, being able to move the stop 56 linearly from a transport device 57 linearly and parallel to the support 54 in the direction of the opening o39 of the printing mold tank 39, for transporting this first printing mold 37 through a translational movement, and preferably without deformation, taking it out of the tank 44, at least until the hanging side 13 is can hook on the leading end 03 of this first mold of printing press 37 in the opening 09 in the form of a groove of the cylinder gravure 33. The stop 56 serves, in this way, in the tank 44, for first printing mold 37, as contact position, and has also at the same time the function of a pin 56. While this first printing mold 37 on the hanging side 14 presents in its end 04 advanced at least one registration die, the top 56 may be formed, for example, also advantageously as a registration bolt 56 attached perpendicular to the support 54 with the transport device 57, so that with the contact of the first printing mold 37 with the contact 56 is made to he a previous record referred to his lateral record. He transport device 57 is shaped, for example, as a belt drive 57 or as a linear drive 57, preferably as a pneumatic linear drive 57, in particular as a linear drive 57 without piston rod, To act on both sides.

In Cuba 44 there is a device for clamping 58, in particular a mold clamping device of printing press 58 for securing at least a second mold of press 37 to be mounted on the gravure cylinder 33. As shown in Fig. 13, the second mold of printing press 37 is held by the clamping device of printing molds 58 above support 54, that is, at a distance a54 from support 54, for example, thanks to the fact that the printing mold clamping device 58 present, for example, on the side opposite the cylinder of gravure 33 a piston 59 movable in parallel to the support 54 or a pin 59, at whose end an element of clamp 61, for example an elbow 61 shaped in the form of "L", in which the second printing mold 37 is held by above the support 54 between the elbow 61 of the extended pin 59 and another fastener 62 arranged in the region of the opening o39 of the printing mold tank 39, for example a stop 62 rigidly arranged. The distance a54 presents in this case a value that is preferably between double and four times the length 114 of the pendant side 14 at the end 04 delayed the second printing mold 37. The clamping of the second printing mold 37 is made thanks to the fact that a separation a58 between elbow 61 of extended pin 59 and the stop 62 fits shorter than the extended length L of the second printing mold 37. The stop 62 in the region of the opening o39 of the printing mold tank 39 preferably has a bevel 63 on which the hanging side 13 can be supported at the end 03 ahead of the second printing mold 37, being opposed between yes the bevel 63 of the stop 62 and the elbow 61 shaped as "L" on which the hanging side 14 rests on the end 04 delayed the second printing mold 37. Since the second printing mold 37 is flexible, in particular, along its length L, this is bulged in its subject state between elbow 61 and the stop 62. The pin 59 of the mold clamping device of printing press 58 can preferably be moved in parallel linear fashion to support 54, and preferably has two operating positions stable, specifically, a stable operating position in the introduced state, which releases the second printing mold 37, and in the extended state, that is, in the state that holds the second printing mold 37. In a variant for the device printing mold holder 58 are interchanged with each other arrangements of the mobile pin 59 and the rigid stop 62, so that the pin 59 is in the region of the opening o39 of the printing mold tank 39 and the stop 62 is in the opposite side with respect to the rotogravure cylinder 33. Alternatively to the linear mobility described, elbow 61 or butt 62 can also be tilted around of a parallel oriented tilting axis in relation to the width B of the printing mold 37. A printing mold 37 attached between elbow 61 and stop 62 is in its position of top or first storage while a mold of printing press deposited on support 54 adopts in this state a second lower storage position, being stored from intermediate mode the printing mold 37 in the second position of storage before transport to the cylinder gravure 33. By means of a drive, preferably by means of a remotely operated drive, for example, from a command post belonging to the printing machine, change the printing mold 37 inside the tank 44 from a first storage position superior to a second position bottom storage. Printing molds 37 stored in the first storage position and in the second position of storage are distanced from each other, for example along of its length L with distance a54, so that they do not touch each other, and as a consequence they cannot be damaged.

Another embodiment of the device printing mold holder 58, which, advantageously, allows a specially reduced constructive height for tank 44, envisages holding the second printing mold 37 above the support 54 extending in the axial direction of the cylinder of gravure 33 in a single plane with at least one element of clamp 64 in a superior storage position, being shaped the clamping element 64, for example, as a rail of guidance 64, preferably as two guide rails 64 which they run parallel to each other (Fig. 7 to 9), holding the rails of guided 64 the second printing mold 37 found in the cuba 44 on its two longitudinal sides along at least one part of its length L in the upper storage position. The printing mold clamping device configuration 58 with guide rails 64 presupposes that the hanging sides 13; 14 at ends 03; 04 of the second printing mold 37 is not they extend along the entire width B of the printing mold 37, not approaching the longitudinal sides of the mold printing 37. The longitudinal sides of the printing mold 37 conform with it in the region of the support surface 02 of the printing mold 37 a protruding end relative to the sides pendants 13; 14. This outgoing end is necessary to make the printing mold 37 can be guided in the guide rails 64. The fastener 64, in particular each guide rail 64, it is formed, for example, by a "U" shaped arch, which surrounds one of the longitudinal sides of the printing mold 37 with a certain clearance, in which the second mold can be introduced of printing press 37 from the side opposite the gravure cylinder 33. With this, the second printing mold 37 is held by the guide rails 64, preferably in a narrow region of its side, acting the clamping, in particular, as a support vertical, and with it, as a support against the force of gravity FG acting on the printing mold 37. Guiding rails 64 they are preferably made of a stable material in form, such as metal or plastic.

To deposit a second printing mold 37 held by the guide rails 64 on the support 54, it must be be able to move at least one of the guide rails 64 in the width B direction of the second printing mold 37. Preferably, however, the two guide rails 64 have been of being able to move along the width B of the second mold of press 37 in opposite directions, so that they separate each other at least temporarily, and increase your distance from each other such that they no longer support the longitudinal sides of the mold printing press 37 vertically, thanks to which the second mold of printing 37, as a consequence of the force of gravity FG that act on it, fall between through the guide rails 64 on the support 54. In case the fastener 64, in a first operating state, hold the second printing mold 37, for example, by means of an electric or magnetic force in the upper storage position, then the element of clamp 64 changes, preferably remotely controlled, from its first state of operation even a second state of operation, making the second operating state that the clamping element 64 make the printing mold 37 and the clamping element 64 be separate from each other, and the printing mold 37, when releasing the element clamping 64 in the tank 44, through a free fall, and with this, only by means of the force of gravity FG that acts on him, change to the storage position that is directly vertically below the position of top storage The second printing mold 37 is fastened in the lower storage position, and also in the upper one, in tank 44, with an inclination of at least 15 °, preferably horizontally At least, the 64 shaped guide rails as a support for the second printing mold 37, present in its longitudinal extension is only light inclination, or a horizontal evolution.

A detachment of the second printing mold 37 from the guide rails 64 that attack you laterally preferably supports by means of a stop 67 that is arranged perpendicular to the support surface 02 of the second mold of press 37, which is preferably rigidly arranged in the Cuba 44, being preferably arranged on both sides lengths of the second printing mold 37 a stop such that during an opposite movement oriented along the width B of the second printing mold 37 from the guide rails 64 holding this printing mold 37, this printing mold 37, by means of the two stops 67 arranged on both sides in the plane held by the support surface 02 of the printing mold 37, Stay stable in position. The stops 67 release the mold of printing 37 of the guide rails 64 that move away from each other, colliding for this the printing mold 37 with the stops 67, while removing the printing mold 37 by means of the movement of the guide rails 64 the vertical support. He detachment of the second printing mold 37 is performed preferably by means of a drive 69 controllable from the command post belonging to the printing machine, in which drive 69 acts on the guide rails, and moves them along a s68 regulation path.

While on the gravure cylinder 33 must be arranged in their axial direction, next to each other, several printing molds 37, and in tank 44, in axial direction of the rotogravure cylinder 33 are arranged, next to each other, several printing molds 37, it is advantageous to arrange the rails of Guided 64, which attack 37 adjacent printing press molds 37, in the printing mold store 39 above support 54 in two different planes, that is, vertically displaced from each other, preferably disposed alternately displaced in the axial direction of the gravure cylinder 33 the planes consecutive. Through the displaced displacement of the planes that make up the first storage position of the cylinders  gravure 33 can be kept as small as possible distance a67 between printing molds 37 arranged one next to another in the axial direction of the gravure cylinder 33, is say, contiguously. The distance a67 corresponds in its value, preferably, with a distance presented by the molds printing 37 arranged on the intaglio cylinder 33 one next to another in its axial direction, that is, contiguously. The printing molds 37 carried from planes arranged one next to the another in the axial direction of the gravure cylinder 33, is say, respectively, from a first position of storage, deposited on support 54, and with it, carried to their second storage position they can be supplied with the transport device 57 to the rotogravure cylinder 33 or either individually, or preferably at the same time so common, the latter being advantageous for a rapid change of molds of printing 37 in the rotogravure cylinder 33. The molds of printing press 37 stored in the axial direction of the cylinder gravure 33 in different planes arranged next to each other they can change at the same time, or at least in a quick sequence, to its second corresponding storage position. Baking tin of printing press 37 supplied to the rotogravure cylinder 33 thereto common mode time are arranged next to each other over the rotogravure cylinder 33 in its axial direction.

In the example shown in Fig. 8 they are arranged four second printing molds 37, respectively, in its first storage position in the axial direction of the gravure cylinder 33 next to each other, each subject being held one of these printing molds 37 respectively on its sides in a guide rail 64. The displacement vertical of the printing molds 37 has a value in this case of only a few millimeters, for example from 4 mm to 6 mm, and corresponds approximately to the constructive height of the guide rails 64, preferably with its constructive height single or double. The movement of the guide rails 64 to the length of the width B of the second printing mold 37 is realized, for example, by means of a linear displacement of the rails of guidance 64; although it can also be done through a tilt movement of the guide rails 64, being tilting the guide rails 64 around an axis of tilt, running the tilt axis parallel to the side of the printing mold 37 supported by guide rails 64. Of this mode, a guide rail 64 may be placed, for example, in at least one tilt arm 68, which can be tilted, for example, in the plane held by the support surface 02 of the second printing mold 37, which is indicated in Fig. 9 by Middle of a direction arrow. Tilt arm 68, one whose ends are connected with the guide rail 64, and whose another end is preferably fixedly arranged in the tank 44, may be shaped as a spring element 68 that acts laterally in the guide rail 64, for example it may be shaped like a laminated spring 68, moving the rail of guided 64 connected with the tilting arm 68 by means of the drive 69, for example by means of a controllable magnet 69, in particular remotely controllable, to a position of operation that holds the second printing mold 37, or to a operating position that emerges from this mold of press 37. The s68 regulation path that a lane of mobile guidance 64 along the width B of the second mold of printing press 37 is in the range of a few millimeters, by example between 2 mm and 10 mm, preferably 4 mm. Preferably also in this embodiment variant a stop 67 is provided, with which the printing mold 37 stops with its side supported along the guide rail 64, while the guide rails 64, through its movement, remove the support to the printing mold 37. Two printing molds 37 contiguous in the axial direction of the gravure cylinder 33 can butt in this case on sides opposite of the same stop 67. During the change from the position of upper storage to the lower storage position, the printing mold 37 can also slide with one of its sides in the stop 67 oriented vertically downward, so that the printing mold 37 released from the storage position superior will stop in a guided movement to the position of bottom storage. The stop 67 then has for a mold of printing press 37 that changes its storage position the function of a lateral guide that preferably reaches support 54.

In general, a procedure for storage of at least two elevators 01; 36; 37 removed from same cylinder 06; 31; 33 of a printing machine one after another It provides the following steps: a) an elevator 01; 36; 37 removed previously from cylinder 06; 31; 33 is transported from a first to a second storage position, b) the elevator 01; 36; 37 removed after elevator 01; 36; 37 removed previously stored in the first storage apposition of elevator 01; 36; 37 previously removed, c) elevator 01; 36; 37 previously retired in his second position of storage, and elevator 01; 36; 37 removed then in your first storage apposition of elevator 01; 36; 37 previously removed are stored at an orthogonal distance at along its length L, d) the elevators 01; 36; 37 are stored in its corresponding support surface 02, at least overlapping in for the most part, preferably overlapping at least up to 80%, or overlapping completely or almost completely. The elevator 01; 36; 37 previously removed and elevator 01; 36; 37 retired to then they can be stored in this case throughout their L length vertically, or also horizontally distanced from each other. Preferably, the elevator 01; 36; 37 previously removed is transported by movement linear, in particular by means of a linear movement that unites each other directly the two storage positions, orthogonal to its support surface 02, or by means of a movement of its 04 end delayed, to its second position of storage, which is explained later in more detail.

It represents an advantage to place, particularly in the tank 44, for example in the pin 56 for a first mold of printing 37 that is on support 54 or also in the angle 61 shaped "L" for a second mold of press 37, a code reader 71, that reads an encoding preferably placed on the hanging side 14 at the end 04 delayed of each printing mold 37, that is, registering a feature for the identification of a printing mold, for check on a comparison preferably done so electronic in the control unit with an occupancy plan provided for the rotogravure cylinder 33, deposited in the control unit, yes the printing molds 37 introduced in the Cuba 44 correspond to the occupation plan of the process of desired printing and / or if for the desired occupation the molds of printing press 37 introduced in Cuba 44 are also in order Right. In this way, before mounting the printing molds 37 on the gravure cylinder 33 a warning is generated corresponding, for example a fault warning, that is, a warning that notifies the handling personnel of an incorrect assembly, and puts, for example in a command post assigned to the mechanism printer, and it is displayed there or in the printing mechanism.

The coding can be shaped preferably, in addition to a code readable by a person,  for example, as a barcode. The code reader 71, with this is arranged in the tank 44 preferably at its end opposite to the rotogravure cylinder 33, a code reader reading device 71 or parallel to the length L of the printing mold 37 or preferably parallel to the width B of the printing mold 37. In one embodiment preferred, the code reader 71 is arranged so that it you can move preferably with a linear guidance inside the Cuba 44, or next to it, or a sliding mirror is provided preferably inclined 45º with respect to the width B of the mold of press 37, which deflects a registration or reading signal from a coding placed in the printing mold 37 to a reader of codes 71 arranged on one side of the tank 44, so that for the reading of the coding placed in the printing molds 37 stored in vats 44 only a single reader of codes 71. Through the use of a single code reader 71 for several 377 stored printing molds can be saved considerable costs. When using a single code reader 71, the code reader 71 or the mirror can be shifted or parallel to the width B of the printing mold 37, that is, in the direction axial of the gravure cylinder 33, preferably along of several vats 44 and / or along the printing molds 37 stacked in one of the tanks 44 vertically in height, of so that the code reader 71 or the mirror registers the coding of printing molds 37 stored in different storage positions Either code reader 71, or at minus another sensor 91 can be used to monitor and / or to check if an intentional printing mold change has been performed successfully. Errors like a double occupation or a incorrect occupation, that is, the assembly of a printing mold 37 in a place that is not correct, can be avoided then, or by less can be verified by means of a given indication preferably at a command post of the printing machine, before from causing major damage.

In Fig. 6 another tank 42 is shown which it is used to house printing molds 37 away from gravure cylinders 33. This tank 42 has a support 72, for inclined example, which, like support 54 in Cuba 44, to provide printing molds 37 to be mounted on the gravure cylinder 33 is preferably formed not flat, but in the form of parallel slats 72 or rails of parallel sliding 72, extending the inclination of the support 72 in the tank 42 preferably on the side opposite the cylinder of gravure 33, thanks to which this Cuba 42 has a better access on the opposite side to the gravure cylinder 33 for a handling person, which facilitates the extraction of the molds of press 37 deposited in Cuba 42. Support 72 in Cuba 42 is inclined relative to a horizontal H at an angle of inclination δ, the angle of inclination δ, for example, between 5 ° and 15 °, preferably of approximately 7º. In the example shown in Fig. 6, the tank 42 for housing printing molds 37 away from the rotogravure cylinder 33 is located below a tank 44 to provide printing molds 37 to be mounted on the gravure cylinder 33, which is certainly a Preferred provision, although not mandatory. The vats 42; 44 they can be stacked in the opposite order, or they can be arranged separated from each other.

A preferred configuration of tank 42 provides that in the tank 42, in the axial direction of the cylinder of gravure 33 can be stored next to each other at least two printing molds 37. This configuration makes a withdrawal possible especially fast of printing molds 37, in particular when in the gravure cylinder 33 in its axial direction they must be arrange at least two printing molds 37 since several molds of printing press 37 can be removed at the same time by the cylinder of gravure 33. When gravure cylinder 33 can be arrange in its axial direction, for example at least four molds of printing 37, then, for stability reasons it is advantageous, for example, arrange two vats 42 in the axial direction of the gravure cylinder 33 next to each other. Each space of storage defined by the width B of a mold press 37 in one of these vats is then made up of such so that there can also be stored so many molds of printing 37 as printing molds 37 can be arranged in the gravure cylinder 33 along its contour, performing the storage of printing molds 37 in each position of storage one over another in a stack. It may be provided that up to ten can be stored in each of the tanks 42, at less up to eight printing molds 37, so that the molds of printing press 37 removed by gravure cylinder 33 can be collect in tanks 42, and tanks 42 are not to be emptied necessarily after each change of printing molds 37 by the management staff. Regardless of the number of the vats 42 arranged next to each other, the positions of storage in the axial direction of the gravure cylinder 33 have the same narrow distance from each other as the molds of printing press 37 that are arranged in the gravure cylinder 33.

On the side opposite the gravure cylinder 33, Cuba 42 presents printing molds 37 for housing removed from the rotogravure cylinder 33 at least in the state of operation in contact with the rotogravure cylinder 33 a guiding element 73 arranged near the side surface 07 of the rotogravure cylinder 33, which is shaped, for example, in the form of a conductive plate 73, a wedge 73 or an element  rolling 73, for example a roller, and which has the mission of bring the delayed end 04 of a printing mold 37 that is if removed from the rotogravure cylinder 33 to the tank 42. A distance a73 of the guide element 73 from the surface side 07 of the rotogravure cylinder 33 is preferably not much greater than the length 114 of the pendant side 14 folded in the delayed end 04 of the printing mold 37, in particular the distance a73 of the guiding element 73 has a value between one and twice the length 114 of the pendant side 14 (Fig. 6). Since a printing mold 37 to be removed from the cylinder of gravure 33 touches with its side of the print arrangement the guiding element 73, its contact with a rolling element 73 housed in a rotating way it is more careful for its surface than a sliding on a rigid wedge 73 shaped flat. This aspect is especially important when the mold of printing press 37 must be reused, and thus avoid damage to your side of the print layout by means of scratches or rubbing marks. In the guiding element 73 it can be placed a sensor 91, which either checks, or in contact with the printing mold 37 to be removed from the cylinder gravure 33, or advantageously, without contact, for example, of inductive mode, if the hanging side 14 has really come off at the delayed end 04 of the printing mold 37 to be remove from gravure cylinder 33 after a drive of the clamping means 21 arranged in the channel 08 of the cylinder gravure 33. With its checking, sensor 91 sends a signal, for example, to the command post belonging to the machine printer. From the signal received by sensor 91, it is decided if the process of removing a printing mold 37 that has been to withdraw from the rotogravure cylinder 33, continue, or if well, measures must be initiated to eliminate a fault. At guiding element 73 are provided in the axial direction of the gravure cylinder 33 preferably several sensors 91, by example four or six, specifically at least one sensor 91 for each printing mold 37 that can be arranged alongside others in the intaglio cylinder 33 in its axial direction.

In a preferred embodiment, the side pendant 14 is placed at the 04 end of the mold delayed printing press 37 to be removed from the gravure cylinder 33 after the passage of the guide element 73 occurs preferably at a first ramp 74 arranged at a certain distance of guiding element 73, before it reaches support 72 in the Cuba 42, climbing the first ramp 74 in the direction of support 72 first, and falling back after a peak point 76 towards the support 72. The first ramp 74 is preferably joined rigidly with support 72. In the progress of the introduction of the printing mold 37 to be removed from the cylinder of gravure 33 in tank 42, its hanging side 14 collides in the end 04 delayed with a second ramp 77, whose flank, after from its peak 78, that is, in the opposite part of the gravure cylinder 33, preferably falls abruptly and inclined towards the support 72. In the direction in which the mold of printing press 37 is introduced into tank 42 is ready shortly distance a77 (Fig. 14) behind peak point 78 one stop 79 rigidly connected with the second ramp 77, with which it stops the hanging side 14 at the 04 end of the mold delayed printing 37. The distance a77 has in this case a value of few millimeters, preferably a value of less than length 114 simple, particularly less than half the length 114 of the hanging side 14 folded at the end 04 delayed mold press 37. When the hanging side 14 abuts the end 04 delayed of the printing mold 37 in the stop 79, it is hooked from behind preferably to the second ramp 77, making for so that the hanging side 14 engages in the intermediate space formed by means of distance a77. The second ramp 77 and the butt 79 attached to it can be moved by means of a device of transport 81 in a linear way and parallel to the support 72, for insert the printing mold 37 into the tank 42 completely must be removed from the rotogravure cylinder 33. The transport 81, which conforms, in particular, together with the Slope flank on second ramp 77 for hanging side 14 folded at the end 04 delayed of the printing mold 37 a drive device that carries the printing mold 37 to the Cuba 42, is shaped, for example, as a drive by belt 81 or as a linear drive 81, preferably as a pneumatic linear drive 81, in particular as a linear drive 81 without piston rod acting by both sides. Both the first ramp 74 and the second ramp 77 are not formed, for example, by full surface planes, but by several guide rails arranged parallel, like the spikes of a hair comb. The second ramp 77 may be shaped, for example to from one or several metal strips folded so correspondent.

On the opposite side of the gravure cylinder 33 an elevator 82 is arranged in the tank 42, in particular a press mold elevator 82, presenting the mold elevator printing press 82 for example a piston 83 that can be moved preferably perpendicularly with respect to the support 72, in which end is arranged a loading arm 84 formed for example, in the form of "L", in particular in the form of "U", placing the hanging side 14 folded at the end 04 delayed of the printing mold 37 on the loading arm 84, or adjusting so that surrounds it. The mold press elevator 82 presents preferably two stable operating positions, in concrete a stable operating position with the plunger introduced 83, in which the loading arm 84 is located by below the level defined by means of support 72, and another position stable operation with extended piston 83, in which the loading arm 84 lifts the printing mold 37 from the support 72 removed from the gravure cylinder 33. The mold lift printing 82 in this case performs a s82 run that is greater than the length 114 of the pendant side 14 folded at the end 04 delayed printing mold 37. Preferably, race s82 it has a value between one and two times the length 114 of the side pendant 14. The press mold elevator 82 thereby raises a printing mold 37 removed from the rotogravure cylinder 33 from a first provisional storage position to a second definitive storage position.

Above the mold press elevator 82, in particular above its loading arm 84 is arranged an insurance element 86 that can be swung around a tilt axis that runs essentially parallel to the width B of the printing mold 37, for example in the form of a cover 86 in the form of a ribbon, whose lower edge is one distance a86 from the loading arm 84, the dimension being  distance a86 preferably with a value less than the length 114 of the pendant side 14 folded at the end 04 delayed the printing mold 37. In Fig. 6, a direction arrow indicates the tilting capacity of the insurance element 86. The element insurance 86 ensures a printing mold 37 raised by the press mold lift 82 against unwanted slippage in tank 42, or against a withdrawal from tank 42. Thus, a driving person must first swing the element of security 86 before the printing mold can be removed 37 raised from the tank 42.

Another embodiment for groups constructs arranged in the tank 42 is represented in Fig.  10 to 12. This exemplary embodiment provides a stop 79 provided with rigid mode preferably in the central region of the support 72, in which an elevator of the printing mold 82 connected with a device transport 81 in a linear fashion along the support 72 lifts the hanging side 14 folded at the end 04 delayed of a mold press 37 to be removed from the gravure cylinder 33 above the stop 79, and carries the printing mold 37 on its side 14 pendant folded preferably in its elevated elevation  from the printing mold 82 to the end of the tank 42 opposite the gravure cylinder 33. The transport device 81 and the print mold elevator 82 may be coupled so forced in such a way that the mold press elevator 82 raises the folded hanging side 14 of the printing mold 37 so soon as the transport device 81 performs a movement in the opposite direction to the rotogravure cylinder 33. In addition, between the stop 79 and the end of the tank 42 opposite the cylinder of gravure 33 is provided another elevator of the printing mold 87 raising the leading end 03 of a printing mold 37 removed from the rotogravure cylinder 33, inserted into the tank 42, until another printing mold 37 to be removed from the intaglio cylinder 33 can be inserted between support 72 and the printing mold 37 raised in the tank 42.

From Fig. 13 to 35, they are now explained, in particular, procedures for changing printing molds 37 in a gravure cylinder 33. It is based on the fact that in the upper tank 44, for the preparation of new molds of press 37 to be mounted on the gravure cylinder 33 two printing molds 37 are arranged, of which on the gravure cylinder 33 along its contour are placed two printing molds 37, and that the bottom tank 42 It is empty to house 37 printing molds removed of the rotogravure cylinder 33, that is, it is free for molds of printing 37.

The gravure cylinder 33 rotates the opening 09 of channel 08 in which the hanging side 14 is held in the leading end 04 of the printing mold 37 to be removed of the rotogravure cylinder 33 by a clamping means 21, in a first position that is below the element of guide 73 that belongs to the lower tank 42. The element of tighten 24 controllable, preferably pneumatically operated it contacts the gravure cylinder 33 (Fig. 13).

The control means 23 operable pneumatically preferably tilts the clamping means 21  against the force of a spring element 22, thanks to which the hanging side 14 shakes at the 04 end delayed mold printing 37 as a result of its own elastic tension coming out of opening 09, and abuts the guide element 73. The clamping element 24 placed secures the printing mold 37 against further detachment of the lateral surface 07 of the intaglio cylinder 33 (Fig. 14).

The gravure cylinder 33 rotates against its production direction P, and thereby pushes the 04 end delayed  of the printing mold 37 in the tank 42. With the introduction of printing mold 37 in the tank 42, the hanging side 14 slides in the delayed end 04 of this printing mold 37 first along the guiding element 73, and then placed on the First ramp 74 that belongs to Cuba 42. The hanging side 14 slide the ramp 74 up to its peak point 76, and to continuation reaches support 72. While the element of tighten 24 remains in contact with the gravure cylinder 33, the printing mold 37, by rotating the cylinder of gravure 33 is introduced against its production direction P more in tank 42. In this case, its hanging side 14 at the end 04 delayed also penetrates the second ramp 77 connected with the transport device 81, and collides with the stop 79 connected with the second ramp 77 (Fig. 15).

The clamping element 24 is removed from the cylinder gravure 33. By means of the collision of the hanging side 14 of the end 04 delayed at the stop 79 separates the hanging side 13 folded preferably hung by drag on the edge front 16 of the opening 09 at the leading end 03 of the mold printing 37 of the opening 09. The printing mold 37 is find now with its 03 end freely advanced on the side surface 07 of the rotogravure cylinder 33. The cylinder gravure 33, from the detachment of the hanging side 14 in the 04 end delayed so far has done less than half turn. The hanging side 14 folded at the end 04 delayed has been hooked between the second ramp 77 and the stop 79. The device of transport 81 connected with the second ramp 77 and with the stop 79 you can now remove the printing mold 37 completely in the Cuba 42 (Fig. 16).

The printing mold 37 is now removed from the gravure cylinder 33, and is now in tank 42 according to its position L, its hanging side 14 at the 04 end delayed it is located on the peak point 78 of the second ramp 77, while its leading 03 end is about the point of peak 76 of the first ramp 74, thanks to which at least the side pendant 13 hangs freely at the end 03 forward. He Housing of the printing mold 37 in the tank 42 is carried out according to this preferably by means of a support in two points, in concrete over peak points 76; 78 of the two ramps 74; 77 (Fig. 17).

The elevator of the printing mold 82 operable, for example, pneumatically, elevates the printing mold 37 removed in tank 42 at its end 04 delayed until a little by under the secure element 86, the hanging side 14 being on the loading arm 84 connected to the press mold lift 82 (Fig. 18).

While a first printing mold 37 that has to be mounted on the gravure cylinder 33 is with its hanging sides 13; 14 bent over support 54 in the tank 44 upper, the gravure cylinder 33 continues to rotate against its production direction P to a second position, until the opening 09, from which the hanging side 13 has detached in the advanced 03 end of printing mold 37 removed previously of the rotogravure cylinder 33, a point of contact 88 of the clamping element 2 4 placed in contact with the gravure cylinder 33, and the rear edge 17 of the opening 09 in the production direction P of the gravure cylinder is is located a distance a88 from the point of contact 88, the distance a88 being in the range of a few millimeters, preferably having a value of less than 30 mm, and with it corresponding to an arc length of less than one thirtieth contour part of the gravure cylinder 33. The first position of the rotogravure cylinder 33 for the removal of a printing mold 37 arranged on it, as a rule, is not identical with the second position for housing a new printing mold 37. The clamping element 24 is placed preferably in the rotogravure cylinder 33, while the opening 09 passes the contact point 88, or after there is past contact point 88. The orientation device 51 arranged near the gravure cylinder 33 swings with its stops 52; 53 diametrals oriented previously preferably of horizontal mode preferably 90º to a vertical position, of way that a stop 52; 53 adjusted to the width of a mold press 37 to be mounted on the gravure cylinder 33 it is introduced in a transport plane defined by means of the support 54 in the tank 44 for the printing mold 37 to be mounted on the rotogravure cylinder 33, and the printing mold 37 which it must be mounted on the gravure cylinder 33 during its transport from tank 44 to stop 52; 53 is oriented according to lateral registration towards the rotogravure cylinder 33 (Fig. 19).

The first printing mold 37 to be mount on the gravure cylinder 33 is in contact with its hanging side 14 at its end 04 delayed with the stop 56 attached with a transport device 57. The transport device 57 is puts into operation, so that the stop 56 carries in a movement oriented preferably tangentially on the rotogravure cylinder 33 the first printing mold 37 up such point taking it out of Cuba 44 until its end 03 advanced touches the clamping element 24 placed in contact with the cylinder gravure 33, and the pendant side 13 folded at this end 03 advance is between the rear edge 17 in the direction of production P of the rotogravure cylinder 33 of the opening 09 and the contact point 88 of the clamping element 24 on the cylinder gravure 33 (Fig. 20).

The gravure cylinder 33 modifies its direction of rotation and begins to rotate in its production direction P, thanks to which the hanging side 13 placed on the cylinder gravure 33 slides on the leading end 03 of the mold printing 37 in the opening 09 and is preferably hung by drag on the leading edge 16 of the opening 09 (Fig. twenty-one).

By means of the subsequent rotation of the cylinder gravure 33 in its production direction P, the mold of printing press 37 hung with its hanging side 13 in opening 09 se transported completely out of the tank 44, and mounted on the gravure cylinder 33. During assembly, the mold of printing press 37 is laminated on the rotogravure cylinder 33 by middle of the clamping element 24 placed in contact with the rotogravure cylinder 33. After half a revolution of gravure cylinder 33 in its production direction P, the clamping element 24 presses the folded side 14 folded into the leading end 04 of the printing mold 37 in the opening 09. The clamping means in channel 08 belonging to this opening 09 it was loose, and then it takes the position of operation in which it fixes the hanging side 14 introduced in the opening 09 at the delayed end 04 of the printing mold 37, by example by means of a tightening. The transport device 57 brings the stop 56 back together with him back to his position end opposite the gravure cylinder 33 in the tank 44 (Fig. 22).

The clamping element 24 is separated from the gravure cylinder 33, and orientation device 51 swings with its stops 52; 53 diametrals again preferably to a horizontal position. With the steps of the procedure described so far a change of a first mold of printing press 37 in the rotogravure cylinder 33, removing it a used printing mold 37, and placing a new mold of printing 37. This change of a printing mold 37 can be carried performed completely with the device described in a very short time briefly, preferably in less than a minute. The cylinder of gravure 33 below is now ready for production (Fig. 23).

The change of another second printing mold 37 arranged, for example, in the rotogravure cylinder 33 at along its contour, start with that preferably during the pre-production has been introduced by a person handling the second new printing mold 37 in the vat 44. In this case, the second printing mold 37 is held by means of a printing mold clamping device 58 controllable, preferably pneumatically controllable, by on the support 54, holding the printing mold 37, for example, or at its ends 03; 04 between two stops 61; 62, being able to move at least one of the stops 61; 52, or the mold of printing press 37 is inserted in its longitudinal sides in guide rails 64, moving at least one of the rails of guided 64 along the width of the printing mold 37. When the printing mold clamping device 58 releases the mold of printing 37, making its elements that hold the mold of printing 37, for example the stops 61; 62, or the guide rails 64, increase your distance from each other at least briefly, for example a58, then the printing mold 37 falls on the support 54 and is it is placed there with its hanging sides 13; 14 (Fig. 24).

To remove, for example another second mold of printing press 37 of the rotogravure cylinder, the cylinder of gravure 33 rotates correspondingly to the procedure explained in Fig. 13 the opening 09 of the channel 08 in which hold the hanging side 14 at the end 04 delayed from the second printing mold 37 to be removed from the cylinder of gravure 33 by a clamping means 21, at the first position below the guide element 73 that It belongs to Cuba 42 below. The clamping element 24 controllable, preferably pneumatically operable, is placed in the gravure cylinder 33 (Fig. 25).

Corresponding to the procedure explained in Fig. 14, the control means 23 operable preferably pneumatically tilts the means of clamping 21 against the force of the spring element 22, thanks to which the hanging side 14 shakes at the delayed end 04 of the second printing mold 37 as a result of its own tension elastic coming out of the opening 09, and collides with the element of guided 73. The clamping element 24 placed secures the second printing mold 37 against other surface detachment side 07 of the rotogravure cylinder 33 (Fig. 26).

The gravure cylinder 33 rotates against its production direction P, and thereby pushes the 04 end delayed  of the second printing mold 37 in tank 42. In the introduction of the printing mold 37 in the tank 42, the hanging side 14 slides at the delayed end 04 of this printing mold 37 first place along the guiding element 73, and placed at continuation on the first ramp 74 that belongs to Cuba 42. The hanging side 14 of the second printing mold 37 slides along the ramp 74 up, moving under the first mold of printing press 37 that rests in Cuba 42, which is located in the peak point 76 of the first ramp 74, and elevates its end 03 forward protruding at peak point 76 facing the gravure cylinder 33, while the pendant side 14 of the second printing mold 37 exceeds the peak of the first ramp 74, and then reaches support 72. While the clamping element 24 remains in contact with the cylinder intaglio 33, the second printing mold 37 is introduced by rotating the gravure cylinder 33 against its production direction P in tank 42. In this case, the side pendant 13 slides on the leading end 03 of the first mold of printing press 37 that rests in tank 42 above the side of the printing arrangement of the second printing mold 37 transported to tank 42. In the subsequent course, the side pendant 14 exceeds the delayed end 04 of the second mold printing 37 also the second ramp 77 connected with the device of transport 81, and collides with the stop 79 joined with the second ramp 77 (Fig. 27).

The clamping element 24 is removed from the cylinder gravure 33. By means of the collision of the hanging side 14 of the end 04 delayed with the stop 79 detaches the hanging side 13 folded preferably hung by drag on the edge 16 front of the opening 09 at the leading end 03 of the second printing mold 37 of the opening 09. The hanging side 13 with its 03 advanced end is now free on the side surface 07 of the rotogravure cylinder 33. The cylinder gravure 33, from the detachment of the hanging side 14 at the end 04 delayed so far has returned to perform less than half turn The hanging side 14 folded at the end 04 delayed it hooks between the second ramp 77 and the stop 79. The arm of load 84 of the mold press elevator 82 is lowered, by means of which the first printing mold 37 held so far by him in its delayed end 04, which rests in tank 42, is placed on a nerve 89 formed in the stop 79, the nerve 89 presenting a h89 height perpendicular to the support 72 whose value is greater that the length 114 of the pendant side 14 at the end 04 delayed of the second printing mold 37. The height h89 presents preferably a value between one and two times the length 114 of the bent pendant side 14 at the end 04 delayed from the second printing mold 37 (Fig. 28).

The transport device 81 connected with the second ramp 77 and stop 79 now introduces the second mold of printing press 37 completely in tank 42, with one on another the first and the second printing mold 37 in Cuba 42 according to its length L. The transport device 81 forms together with the second ramp 77 and the stop 79 for the side 14 pendant folded at the end 04 delayed printing mold 37 introduced into the tank 42 a dragging device (Fig. 29).

The press mold elevator 82 now elevates with its loading arm 84 preferably the delayed end 04 of the two printing molds 37 arranged in tank 42 until the insurance element 86. The leading end 03 of the second mold of printing press 37 encounters a bay facing the gravure cylinder 33 over the peak point 76 of the first ramp 74, and the hanging side 13 angled at the end 03 forward of the first printing mold 37 protrudes over the end 03 front of the second printing mold 37 (Fig. 30).

For mounting the second printing mold 37 which is located in the upper tank 44, the gravure cylinder  33 keeps turning against its production direction P back in the second position until opening 09, from which it has been detached the pendant side 13 at the leading end 03 of the second printing mold 37 removed from the gravure cylinder 33, the contact point 88 of the clamping element 24 has passed placed in contact with the rotogravure cylinder 33, and the edge 17 rear of the opening 09 in the production direction P of the rotogravure cylinder 33 is located at a distance a88 with respect to the contact point 88, the distance a88 being in the range of a few millimeters, having a value, preferably, less than 30 mm, and thus corresponding to a length of arc of less than one thirtieth part of the cylinder contour of gravure 33 (Fig. 19). The clamping element 24 is placed preferably in the rotogravure cylinder 33, while the opening 09 passes through contact point 88 or after past contact point 88. The orientation device 51 arranged near the gravure cylinder 33 swings with its stops 52; 53 diametrals previously oriented in one way preferably horizontal preferably 90º to a position vertical, so that a stop 52; 53 adapted to width B of second printing mold 37 to be mounted on the cylinder gravure 33 is immersed in a defined transport plane by means of the support 54 in the tank 44 for the second mold of press 37 to be mounted on the gravure cylinder 33, and the second printing mold 37 to be mounted on the rotogravure cylinder 33 is oriented during transport from the tank 44 at the top 52; 53 oriented according to lateral registration towards the rotogravure cylinder 33 (Fig. 31).

The second printing mold 37 to be mount on the gravure cylinder 33 is in contact with its pendant side 14 at its end 04 forward with the stop 56 attached with the transport device 57. Correspondingly to the procedure explained in Fig. 20, the transport device 57 is put into operation, so that the stop 56, in a movement oriented preferably tangentially on the rotogravure cylinder 33, transport the second printing mold 37 taking it out of Cuba 44 until its leading 03 end touches the clamping element 24 placed in contact with the cylinder of gravure 33, and the pendant side 13 folded at this end 03 forward is between the rear edge 17 of the opening 09 in the production direction P of the rotogravure cylinder 33 and the contact point 88 of the clamping element 24 on the rotogravure cylinder 33 (Fig. 32).

Corresponding to the procedure explained in Fig. 21, the gravure cylinder 33 modifies its direction of rotation and begins to rotate in its production direction P, thanks to which the hanging side 13 placed in the cylinder of gravure 33 at the leading end 03 of the second mold of printing press slides to opening 09, and preferably hangs by dragging on the leading edge 16 of the opening 09 (Fig. 33).

By means of the subsequent rotation of the cylinder gravure 33 in its production direction P, the second mold printing 37 hung with its hanging side 13 in the opening 09 se transport completely out of the tank 44, and placed on the gravure cylinder 33. During placement, the second printing mold 37 is laminated by means of the clamping element 24 placed in the rotogravure cylinder 33 on the cylinder gravure 33. After half a revolution of the cylinder gravure 33 in its production direction P, the element of press 24 press the folded side 14 folded at end 04 delayed from the second printing mold 37 by introducing it into the opening 09. The clamping means 21 in the channel 08 belonging to this opening was detached, and then carried to the operating position where you set the hanging side 14 introduced in the opening 09 at the end 04 delayed from the second printing mold 37, for example by means of a tightening. He transport device 57 brings the stop 56 back together with it to its final position on the opposite side of the gravure cylinder 33 in Cuba 44.
